TABLE. A comparative analysis of Uca lactea mud-mounds (present study) and Uca marionis mud-volcanoes (De, 2009) produced in the Bay of Bengal coast, India.
| Observed traits | U. lactea mud-mounds | U. marionis mud volcanoes |
| Highest population density | 9/sq m. | 26/sq m. |
| Average vertical height of mounds | 12 cm | 8 cm |
| Mound height variation | Increases from high to low ground | Independent of ground undulations |
| Mound building process control | Tide and mangrove vegetation | No such control |
| Mound stabilization factor | Microbially controlled | No microbial control |
| Burrows within compound mounds | Close spaced, but not connected | Close spaced, but connected at the base |
| Maximum vertical height of mound centric burrow | 21 cm because of higher position of subsurface mud layers | 29 cm because of lower position of subsurface mud layers |
| Association with worm burrows | Present | Absent |
| Mound collapse during high tides | Occurs | Occurs |
| Morphology of simple and compound mounds | Cone and multiple cone | Cone and multiple cone |
